High-temperature resistant busbar is a power transmission device specially designed for high-temperature environments. Here is a detailed analysis of it:

I. Definition and Composition

1.Definition: High-temperature resistant busbars are mainly used to supply power to mobile equipment in places with high temperature, high dust or corrosive gas.

2.Composition: High-temperature resistant busbars usually consist of two parts: the slide rail (fixed part connected to the power supply) and the current collector (sliding part that can slide in the inner cavity of the slide rail and contact the copper conductor to pick up power). The slide rail is generally 6 meters long per single section and can be connected together. In addition, the sheath of the high-temperature resistant and flame-retardant busbar is usually extruded from epoxy resin.

II. Characteristics and Performance

1.High temperature resistance: High-temperature resistant busbars can withstand high-temperature environments, and some products can even withstand high temperatures up to 1000℃. The sheath extruded from epoxy resin usually will not soften or burn at 230℃.

2.Fire resistance: High-temperature resistant busbars are not easy to burn themselves, and they are non-toxic and harmless in case of fire, and will not release harmful gases, which can effectively protect personal and property safety.

3.Safe and reliable: High-temperature resistant busbars are not prone to faults during sliding, with high stability and low contact resistance, which can ensure the safe and stable operation of the circuit.

4.High mechanical strength: High-temperature resistant busbars have high mechanical strength, are not prone to bending deformation, and can withstand particularly strong short-circuit impulse current.

5.Large current carrying capacity: The current carrying capacity of high-temperature resistant busbars can be set according to user needs, usually reaching more than 3000A, and the voltage level remains above 5KV.

6.Low impedance: High-temperature resistant busbars use copper or copper-aluminum conductors, which can greatly reduce the power loss on the wires. After adding auxiliary cables, low-impedance busbars can be formed, and the wire impedance is reduced by half.

7.Flexible wiring: The wiring of high-temperature resistant busbars can slide on the upper or lower part, adapting to different installation requirements.

III. Application Scope

High-temperature resistant busbars are widely used in power and control circuits in various harsh environments such as high temperature, high dust and high corrosion, such as steel smelting, metallurgy, chemical industry, light industry, machinery manufacturing, petrochemical, port loading and unloading and other industries. Especially in coking plants, chemical plants, steel plants, shipyards and other occasions, high-temperature resistant busbars can stably supply power to ensure the normal operation of production equipment.

IV. Installation and Maintenance

1.Installation: The installation of high-temperature resistant busbars should follow certain steps and rules, including environmental inspection, material preparation, safety measures formulation, etc. During the installation process, it should be ensured that the contact between the busbar and the bracket is tight, without loosening or twisting. At the same time, pay attention to the joint treatment of the busbar to ensure that the joint is firmly connected and has good contact.

2.Maintenance: During long-term operation, high-temperature resistant busbars should be regularly inspected and maintained. The inspection contents include the wear of the busbar, whether the joints are loose, whether the insulating materials are aging, etc. Through regular maintenance, the normal operation of the high-temperature resistant busbar can be ensured and its service life can be prolonged.
